Patented Apr. 8, 1930 UNITED STATES PATENT OFFICE WILLIAM M. GOLDSMITH,OF CINCINNATI, OHIO, ASSIGNOR TO THE GOLDSMITH METAL LATI-I COMPANY, OFCINCINNATI, OHIO, A CORPORATION OF OHIO SPREADER FOR USE WITH METALTILES Application filed' March 24, 1927. Serial No. 177,922.

This invention relates to a device for positioning and supporting formsor tiles used in concrete floor construction.

An objectof the invention is to provide 5 means whereby a form or tilemay be retained against displacement and adjustably positioned relativeto a temporary supporting structure for forming a beam of any desireddepth.

Another object is to provide a device which will suspend a form ortile'upon the temporary structure and at the same time precludecollapsing of the tile due to force exerted thereon by plastic concrete.

Another object is to'provide a device for the purposes stated which maybe readily removed after the concrete forming the floor and beams hasset, forpermitting removal of the forms or tiles.

Another object is to provide a device for the purposes stated which maybe cheaply manufactured, and assembled in a manner staph that loss ofits various parts is impossi 1e.

means described herein and disclosed in the accompanying drawings, inwhich:

Fig. 1 is a cross sectional view showing the device of the presentinvention supporting a form or tile about which concrete has been pouredfor forming a floor and beams.

Fig. 2 is a view taken on line 22 of Fig. 1. Fig. 3 is a sideelevational view of the device showing the parts in an inoperativeposition. Fig. 4 is a sectional view on line 44 of Fig. 3. I

The device comprises a housing 8 built up of a pair of identical sideplates 9 and 10 which are preferably sheet metal stampings each havingafiange 11 and a grooved portion 12-. The side plates are secured oneupon another by any suitable securing means such as spot welding 13whereby the grooves 12 in each side plate cooperate for forming abearing for a pair of longitudinally slidable support members or bars 14each having a handle portion 15 and a free end 16. The handle portions15 extend downwardly from the housing through an enlarged opening or way17 in which the handles may be reciprocated These and other objects areattained by the longitudinally of the housing for disposing the free end16 of the support member either within the housing as shown in Fig. 3,or extended from the housing as shown in Figs. 1 and 2 for supportingthe form or tile 18 upon aligned rows of sofiits 19 supported in a wellknown manner upon shoring 20.

Each of the side plates 9 and 10 is provided with a slot 21 extendingfrom the lower edge 22 thereof to a point slightly beyond the bearing orgroove 12 for permitting oscillation of the rods 14 in the bearing 12whereby the handles 15 may assume the operative position shown in Figs.1 and 2. It is obvious that in the above referred to operative position,the free ends 16 of rod or support member 14 are extended beyondthe'housing and may not'be moved from the extended position except bysubsequent oscillation of the handles into the plane of the sidemembers, whereupon the handles are disposed in alignment with way 17 andmay then bemoved longitudinally within the way for drawing the free ends16 into the housing 8.

To preclude accidental movement of the handles 15 from the operativeposition shown in Figs. 1 and 2, a locking device is provided comprisinga lever 23 pivotally mounted upon the housing at 24 and adapted formovement to the position shown in Fig. 2 for locking both handles 15 inthe operative position. A nail 25 or other object may then be passedthrough coinciding perforations 26 and 27 in the lever and housingrespectively for precluding movement of the locking device. To permitready manipulation of the lever 23, a suitable extension 28 may beprovided on the end thereof as shown.

The operation of the device is as follows: After the temporary structurecomprising soflits 19 has been erected, the forms or tiles 18 forforming beams 29 and floor 30 are brought into position adjacent thesoflits 19. The device of this invention with the free ends 16 disposedwithin housing 8 as shown in Fig. 3 is then inserted between the sidewalls 31 of the tiles and handles 15 are actuated to extend the rods orsupport members 14 as shown in Figs. 1 and 2. .Theends 16 of said rodsare received by perforations 32 in the side walls 81 of the form andextend therethrough for a distance suflicient to permit ends 16 to restupon the top surface of sofiit 19 for suspending the form. The handlesare then oscillated to the position shown in Figs. 1 and 2 and locked bylocking device 23. It should be noted that by providing tile 18 with aplurality of perforations 32 for receiving ends 16 of the device of thisinvention the tile may be raised or lowered relative to the soflitswhereby beams 29 of various proportions may be formed.

After positioning aligned rows of tiles in the above manner, plasticconcrete is, poured about the tiles and allowed to set for forming thebeams and floor. It should be noted that concrete forming the beam 29when in a plastic state tends to collapse tile 18 by bending the sidewalls thereof inwardly. The device of this invention being of a lengthsubstantially equal to the distance between the side wa%ls of the tile,precludes collapsing of said wa ls.

After the concrete has set, tiles or forms 18 are to be removed. Thelocking device is first actuated to permit oscillation and movement ofhandles 15 to the position shown in Fig. 3. It should be noted thatmovement of the handle 15 in the slot 21 loosens the end 16 from theconcrete of the beam 29 in which the end 16 becomes embedded while theconcrete is setting. After said ends are thus freed, the support rods 14may be reciprocated to the inoperative position shown in Fig. '3whereupon the entire device may be withdrawn from the inside of the formand the form severed from the concrete.

It should be noted that the construction of the housing 8 as shown inFig. 1 is such that the device will withstand considerable compressionstrain exerted thereon by the side walls 31 when the concrete formingthe beam is poured. Another important feature is the few parts neededfor the manufacture of the device. The parts required are two identicalside plates, two identical support bars 14 and a lever 23 having a pivot24. Exclusive of the pivot 24, it is necessary to manufacture only thethree independent parts above men tioned. The device is assembled sothat there are noloose parts to become detached and lost.
